Anatomical model and method for medical training
Aspects of the present invention are directed to an anatomical model for training that includes a head portion; at least one auricle portion; at least one ear canal; and at least one cartridge. The at least one cartridge may be adaptable to mimic at least one pathology of the human ear, such as an eardrum perforation, a middle ear fluid, a cholesteatoma, a tumor, or earwax.
1. An anatomical model for training, comprising:
a head portion;
at least one auricle portion adapted to be detachably attached to the head portion;
at least one ear canal adapted to be interchangeably connected to the at least one auricle portion; and
at least one cartridge adapted to be removably inserted at the at least one ear canal, the cartridge having a membrane and an interior portion disposed behind the membrane according one of the following:
wherein the interior portion is configured so a vacuum can be created to cause the membrane to retract inward and that can be pressurized to cause the membrane to bulge outward,
wherein the interior portion includes a fluid disposed therein and the membrane is configured to receive an incision that allows the fluid to drain from the interior portion and that holds a pressure equalization tube in the incision, and
wherein the membrane is configured with one more openings so air can flow out of the interior portion during pneumatic otoscopy such that the membrane will move a detectable amount during said pneumatic otoscopy.
2. The anatomical model according to claim 1 , wherein the membrane is configured to simulate a tympanic membrane and the interior portion is configured to simulate a middle ear space, the membrane and interior portion being adaptable to mimic two or more pathologies.
3. The anatomical model according to claim 2 , wherein the two or more pathologies are chosen from an eardrum perforation, a middle ear fluid, a cholesteatoma, a tumor, a retracted eardrum, a bulging eardrum, tympanosclerosis, and earwax.
4. The anatomical model according to claim 1 , further comprising shoulders detachably attached to the head portion.
5. The anatomical model according to claim 4 , wherein the head is adapted to rotate relative to the shoulders.
6. The anatomical model according to claim 5 , wherein the shoulders are detachably attached to the head portion via a neck portion.
7. The anatomical model according to claim 5 , wherein the membrane is detachably attached to the at least one cartridge.
8. The anatomical model according to claim 7 , wherein the membrane is made, at least in part, of at least one plastic.
9. The anatomical model according to claim 1 , wherein the at least one auricle is made at least in part of at least one of at least one silicone, at least one rubber, or at least one polymer.
10. The anatomical model according to claim 1 , wherein the at least one auricle portions includes at least one base portion comprised at least in part of at least one of at least one silicone, at least one rubber, or at least one polymer.
11. The anatomical model according to claim 1 , wherein the head portion is made at least in part of at least one plastic.
12. The anatomical model according to claim 1 , wherein the at least one cartridge is adapted to receive at least one fluid in the interior portion.
13. The anatomical model according to claim 12 , wherein the fluid includes at least one of water, saline, at least one polymer, or at least one hydrogel.
14. An anatomical model for training, comprising:
a head portion;
at least one auricle portion adapted to be detachably attached to the head portion;
at least one ear canal adapted to be interchangeably connected to the at least one auricle portion; and at least one device for simulating two or more pathologies that is adapted to be removably inserted at the at least one ear canal, the device having a membrane and an interior portion disposed behind the membrane according one of the following:
wherein the interior portion is configured so a vacuum can be created to cause the membrane to retract inward and that can be pressurized to cause the membrane to bulge outward,
wherein the interior portion includes a fluid disposed therein and the membrane is configured to receive an incision that allows the fluid to drain from the interior portion and that holds a pressure equalization tube in the incision, and
wherein the membrane is configured with one more openings so air can flow out of the interior portion during pneumatic otoscopy such that the membrane will move a detectable amount during said pneumatic otoscopy.
15. The anatomical model according to claim 14 , wherein the two or more pathologies are chosen from an eardrum perforation, a middle ear fluid, a cholesteatoma, a tumor, a retracted eardrum, a bulging eardrum, tympanosclerosis, and earwax.
16. The anatomic model according to claim 14 , wherein the membrane is configured to simulate a tympanic membrane and the interior portion is configured to simulate a middle ear space.
